Installed but will not start

Hello, i installed total audio converter and updated it with the key. It said to restart, and once i did it will not open. I uninstalled and reinstalled twice, and nothing. I gave it permission in my mcAfee antivirus to accept it. Im using windows 7. Any programs its not compatible with or what might be the problem? thanks

you are kidding, right?! Is this your "solution"?
Disable UAC, reboot, launch TAC, convert Audio, Enable UAC, reboot.
And that everytime you want to convert files?
And yes, I prefer leaving UAC enabled.
Why don't you code like the rest of the world and go with the new standards which UAC is?
When will this TAC error be fixed?
Thanks
